Why are some text messages green or blue? Does my iPhone automatically select?

Text Messages that use a Green Bubble indicate that they were sent using the SMS portion of your carriers service. SMS messages are used widely around the world between mobile phones that are not iPhones.

Text Messages that use a Blue Bubble indicate thet they were sent using the iMessage service from Apple which uses the mobile data portion of your cellular service. iMessages can be used solely between Apple devices (iPhone, iPad, iPod or a Mac).

Yes, your iphone will select the method to be used when messages are sent (based on your settings).
